.To .allwhomktt may. concern:

:Be it :known-fthat .1, SHERMAN M. TANNE- A1HIIaL,-a citizen'ofthe-.UnitedStates of Amerea,:residing` at Connellsville,in the county ofFayette and State of Pennsylvania, have invented certain new and usefulIm rovements -in`MovingPicture Apparatus, o which the following is a secification, reference being had therein to. t e;accompanying drawings.

This -inventon b a paliatusz an 'fits primary o ject is to avoid .it-lieunwin mfrewinding ofthe film st-rip em loyedin meehanismsof this class.

further object of the invention is to pro- -vide rollers orgpulleyslof'novel construction,

and relative arrangement, for guiding the film stri j 1n its travel.

.'lihe invention consists in the combination `with a -moving l.picture'machina vof va film Istri 'having its endsconnectedsto forman.

end ess band; 'and in an endless film strip formed .adjacent l'to its`edges with .perforations to receive-.,thesteeth ofsprocket Wheels fordriving'theendless strip. 1

The invention further consists of means for supporting the endless:lilm-stripain such a manner as to direct theifrontportionyof said stripaway from the sight opening of the apparatus, so that the projection ofthe pictures upon the strip b opticon will not eobstructed.

The construction of the improvement will be fully described? hereinafterin connection .with the accompanying drawing which forms part of thespecification, and its novel features will be defined in the appendedclaims.

In the drawing: Figure l 1s a view in perspective, partly broken awayofa moving 1picture machine embodying the invention,

ig. 2 is a diagrammatic view partl in side elevation and partly inelevation of t e same,

vand Fig. 3 is a detail front elevation showing the oppositely disposedconical .rollers over which the film strip passes. Y .tral longitudinalsectional view of the film box that is supported beneath the machine,

and Fig. 5 is a horizontal sectional view of said frame Y alining withthe lens 5 of the s tereo ticon.

j k Below the table 1 is suspended a box8,-

` the same.

The reference numeral 1 designates a table uponwhich is supported astereopticon 2, and a frame 3 supporting the ilm mechanism, providedwith ai sight opening 4 The revoluble shaft 6 of the film eedingmechanism is provided'withja crank 7.

l'relates A,to moving picture.

-8a between the block 8c means of the usual `stere- Fig. 4 is acen-A `ofthe frame 3 wi formed at its rear end with top With a slot 1 0. Parallelna ed in the walls of the slot 9 orinsuitable brackets providedtherefor, and parallel brackets 13 project from the opposite wallspofthe slot l0 forming bearings fora airv of rollers 14. Below theserollers 1.4 Wit 'n the-.box

8 are supported two shafts y15 Jand' 15a; the

shaft`1'5`carryingaroller l 5 having sprocket wheels 16, while the shaft1 5a carries arolleril 7 provided with grooves 17X to receive theteathof sprocket Wheels 16. Within thefbox 8 is a casing 8a, open at thefront end and closediat therear end. This casing is provided lwith sideflanges 8 by means `of which it isseeured to the innerfaces of theysidewalls ofthe'hox 8. lIn the casing -8a is'a sliding'block 8v ro-g'vided with forwardly-projectin arms 8 :in

which the shaft 15a 1s .j ournaied. hOne or more coil springs 8b ismountedin the casing and the rear endof said casing for the purpose ofholding-:the

roller 17 yieldingly against the roller-15 fear.-

ried by shaft 15. The film is firmlyheld'befv tween the rollers 15 and17 byathe springer springs 8b forcing the block ,80.andzrollerlf7towards roller 15X, thus preventingthelm from being displaced Wlthrelatio'n tothe Sprocket wheels, and also allowing for any unevenness orirregularities in the film'.

Bracket arms 18 'project from the forward side of the frame 3, and insaid arms is. supported a roller 19.'

The numeral 20 designates .the endless film strip formed adjacent toeach of its edges with perforations" 21 to receive the teeth of thesprocket wheels 16. This 'stripy passes through openings 22 and 23formed in the table, and through the'slots 9 and 10 of the box. by abelt (not shown) operating over pulley 24 of the moving picture-machineand over` pulley 15 carried by the shaft 15.

A bracket 25 extends rearward from the frame 3, and mounted in bearings26 depending from said bracket is a 'conical pulley 27. Another conicalpulley 28 is mounted in bracket bearings above an opening 2 9 in theframe 3, through which opening the filmstrip passes.

The two conical pulleys 27 and 28 are oppositely disposed as shown inFig. 3 and are outv of vertical alinemenf so that that portion 30 of thefilm-stri which is moving in front' not obstruct the part of the filmopposite the sight opening.

aslot QI-and-'atits rollers 12 are. jour-1 described.

The endless film strip is also guided by parallel rollers 31 supportedon the front side of the frame 3, and any slack in the film stripwill'fold upon itself within the box 8, as

' shown.

Parts of the feeding mechanism not specifically described are intendedto be repre' sented only conventionally, the characteristic and novelfeatures of the present improvement being the structure above fully forefiectingYI the forward portion of a film strip fedfrom said mechanismout of alinement with the lens of the stereopticon.

2. In a moving picture machine the combination with a stereopticon, of aframe car- 'n the film feeding mechanism, and means v for efiecting theforward ortion of a film strip fed from the fee ing mechanism throughsaid frame, 'comprising oppositely disposed conical pulleys supported inthe A frame in different vertical planes.

3. In a moving picture machine, the combination with a stereopticon, ofa frame sup A ported in front thereof, a box below said frame,film-carryingand. feeding mechanism supported on said frame, land meansfor defiecting a portion of a film strip fed from said mechanism awayfrom the sight opening of the machine.

4. In a moving picture mechanism, the combination with a stereopticon,of a frame i supported in front of said stereopticon, a film-carryingand feeding mechanismsupbtoJ-F ported by said frame,- said frameprovided with an opening to receive a film, a conical roller in saidopening over which the film is drawn as it is fed through the feedingmechanism, a bracket carried by the rear face of the frame and locatedon adifierent plane than .the opening in said frame, a conical rollercarried by said bracket to receive said film, and a film-receiving boxsupported below said frame. l Y

5. In a moving picture mechanism, the combination with a stereopticon,of a frame supported in front of said stereopticon, a film-carrying andfeeding mechanism sup ported by said frame, said frame provided with anopening to receive a film, a conical roller in said opening over whichthe filma' Y ff' Y- drawn as it is fedthrouglrthe feeding'm'echanism, abracket 'carried by the rear face of the frame and located on adifferent vertical plane than the opening in said frame,'a conicalroller in said bracket to receive said film, a film-receiving boxsupported below said frame, and means within said box for holding thefilm strip taut during the feeding operation.

' In testimony whereof I affix my signature in thepresence of twowitnesses.
